Abstract: 【Objective】To date, integrated research of production and consumption of CRFs is lacking. In order to conduct the research, fertilizer cores of CRFs were analyzed to discern improvement of CRF products' controlled-release performance. 【Method】An electron scanning microscope was used to study the core-coating microstructure of 4 fertilizer cores with different granulating processes and their coated CRFs. The influence of different granulating techniques on controlled release performance was analyzed according to a N leaching experiment of 2 CRFs with different cores. 【Result】When the air-cooling core and the disc-core were between the oil-cooled and drum cores, the oil-cooled-core had the smoothest surface, and the drum-core had a porous and coarse surface. While the tower-core and disc-core were between the oil-cooled and drum cores, the oil-cooled-core was very tidy and the drum core was loose. With the tower-core and disc-core in between, the oil-cooled-core had very high compactness in core- coating, the drum core had an obvious gap between core-coating. A soil-column leaching experiment showed that CRF with an oil-cooled-core had a much lower accumulated N leaching rate than that of CRF with drum-core. 【Conclusion】The performance of controlled-release was closely related to different core-coating microstructures. This paper analyzes and discovers the contribution of a CRF core to nutrient release capability improvement.
